General info

Elixir library for browser automation and writing intergration tests

It is a front-end testing library that has support for: Selenium (Firefox, Chrome), ChromeDriver and PhantomJs. Also supports JavaScript applications and retries tests a few times before reporting errors

Kahlan is a full-featured BDD testing framework

It is a full-featured BDD testing framework that embraces the KISS (Keep It Simple, Stupid) design principle. Kahlan makes it possible to write unit tests using the 'describe-it' syntax and requires at least PHP 5.5
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

No

No

Client-side
Allows testing code execution on the client, such as a web browser

Yes

Allows for browser Automation and writing of end-to-end tests for web apps, supports Selenium WebDriver, ChromeDriver, and PhantomJS - GhostDriver

Yes

Kahlan allows you to test front-end components and behaviour easily
Server-side
Allows testing the bahovior of a server-side code

N/A

Yes

You can test individual back-end components using Kahlan
Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

N/A

Yes

Fixtures can be defined by use of 'setUp()'method and cleaned using the 'tearDown()'method
Group fixtures
Allows defining a fixed, specific states of data for a group of tests (group-fixtures). This ensures specific environment for a given group of tests.

N/A

Yes

You can write group fixtures
Generators
Supports data generators for tests. Data generators generate input data for test. The test is then run for each input data produced in this way.

Yes

Not inbuilt but by use of a third party library like ExopData

N/A

Licence
Licence type governing the use and redistribution of the software

Mocks
Mocks are objects that simulate the behavior of real objects. Using mocks allows testing some part of the code in isolation (with other parts mocked when needed)

Yes

Yes, through the use of a third party library like Mockery

Yes

With Kahlan's stubbing system you are able to set stubs (like mocks) directly to your class methods (dynamic mocking)
Grouping
Allows organizing tests in groups

N/A
